Hi Yuchen,
we're using the same way to enable /MP, and it works for us. You didn't say exactly what doesn't
work, so I'm left to guessing.
Have you checked in Visual Studio if the flag is set (Project properties->C/C++->Command Line)?
Maybe there's a conflicting option enabled? Or maybe you're changing the CMAKE_CXX_FLAGS variable
too late, e.g. after calling add_executable()?
Have you checked the value in Tools->Options->Projects and Solutions->VC++ Project Settings->Maximum
...
Best regards,
Andreas

Hi, there!
I am using Windows SDK 7.1 + nmake + CMake for building Windows applications.
Follow these:

I can't make /MP option works after this change in CMake's main CMakeLists.txt
if (MSVC)
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /MP")
SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} /MP")
message(STATUS "CMAKE_CXX_FLAGS = ${CMAKE_CXX_FLAGS}")
message(STATUS "CMAKE_C_FLAGS = ${CMAKE_C_FLAGS}")
endif()
I know Jom which is a good choice for speed up compilation, but some times, it
will broken my builds.
See: http://qt-project.org/wiki/jom
Am I lost some option? does there exist an valid way?
or, It's just a bug from CMake self?
Thanks a lot!
